[PATCH] drm/i915: Fix an error hanfling path in 'i915_gem_do_execbuffer'

[Christophe JAILLET]

if 'eb_create()' fails, we must release some resources as done in all other
error handling paths of this function.

This patch is just a guess based on surrounding gotos and function names.
(i.e. 'get_unused_fd_flags()' and 'put_unused_fd()')
